More and more data centers are upgrading to 40G and beyond, which adds more floor space is an expensive, disruptive and sometimes un-affordable solution. Therefore, we should use high-density products to solve this problem. Then push-pull TAB fiber patch cables were conceived. This high-density patch cable provides improved accessibility, reduced installation costs and outstanding performance for today’s demanding high-density data center applications. In this article, some knowledge of push-pull TAB fiber patch cables will be provided.

Introduction to Push-Pull Tab Patch CablesPush-pull TAB fiber patch cable is a new patch cord with a special “pull” tab design that can help to solve the problems of finger access in high-density cabling. It has the same components and internal-structure as the traditional patch cords, except a tab attached to the connector used for pushing or pulling the whole connector. With this special design, technicians can finish the installing and removing procedures with only one hand and no additional tools are needed. At present, this high-density push-pull TAB fiber patch cable, with either MPO or LC connector, is widely used in 40G and 100G network cabling.

Types of Push-Pull Tab Patch Cables
There are mainly two kinds of push-pull TAB fiber patch cables in the market: LC-HD TAB fiber patch cables and MPO-HD TAB fiber patch cables. The LC-HD TAB fiber patch cable is designed for the LC-HD switchable& movable connector. And its slim uni-boot design saves much space and makes cables more easily to be managed. MPO-HD TAB fiber patch cables can greatly simplify the use of MPO connectivity when manual access to the release slider and rear portion of the connector is restricted. In this way, easy insertion and extraction of MPO patch cords can be achieved.

Advantages of Using Push-Pull Tab Patch Cables
Though traditional patch cables are popular in the data center, the push-pull TAB patch cables have many unique advantages.

Easy to Release Patch Cord

In high-density environment such as 48-port 1U patch panels, inserting and disconnecting patch cords can be challenging for technicians. The flexible pull-tab of the patch cable allows for the connector to be disengaged easily from loaded panels without the need for special tools. In fact, a gentle pull on the tab may disengage the connector from extremely dense fiber patch panels. Furthermore, labeling is also available on the pull-tab so that each cable can be quickly identified.

Higher Flexibility and Adjustabilityfie

Push-pull patch cords are available in various specifications which can connect different generation of devices from 10Gb/s to 120Gbp/s or more. It provides safe and easy push and pull of the specific connector without affecting the other connectors around it. What’s more, high-density and ease of installation provide a low initial investment cost. All these benefits provide a high return on investment.

Space Saving

The traditional connectors often require a small vertical space above and below the adapters. While the low profile push-pull TAB patch cable, together with its pull tab, allow adapters to be stacked with absolutely no vertical space (as in the following figure).

Conclusion
We started with 1G switches. Those switches became 10G. Recently we’ve seen the trend of 40G. In the future, those switches will become 100G and even 120G. It has been proved that push-pull tab patch cords can support high durability and flexibility which fit the connection between devices of different data rate. Fiberstore offers a wide range of push-pull TAB patch cables that will help free up space.We supply simplex&duplex LC-HD patch cords, 12&24 fibers MPO-HD patch cords, MPO-LC harness cables, providing low-loss performance for multi-mode and single mode high speed networks and improving network performance.

There is a common phenomenon that people are always able to distinguish different types of interfaces easily after corresponding to the given pictures, but when we choose the fiber patch cable, such as the polishing type also confused them, it shows UPC or APC, also confused us, recently I finally understand it and share my ideas with you.

First we can look from the definition, the above are acronyms for the following:

UPC – Ultra Physical Contact

APC – Angled Physical Contact

Only from the words we can have a simple understanding of them, in order to have a deeper understanding, there i named a few examples for you. Usually when we hear about the description like “fiber patch lc apc lc upc”, “e2000 fc apc”, “sc apc to sc upc single mode 9 125 simplex fiber optic patch cord cable”, what do this words apc upc mean? Then we will give you explanations. In Fiberstore, We use different color to distinguish them, the blue is UPC connector and the green is APC connector, shown as the figure.

In fact, it stands for the polish style of fiber optic core and connect the copper connector of copper cable as medium, and we need to know that the connections between the fiber optic connector and the ceramic core. Different fiber optic connector ring’s size, length and polished style is different, different polish of the fiber optic connector rings result in different performance, mainly on the back reflection. Generally, UPC is 50dB or higher and APC is 60dB or higher. All insertion loss of that they should be less than 0.3dB and the lower insertion loss is, the better performance they have, it is the reason why UPC connector is more widespread than APC. At the same time, there is a point we need to pay attention to, we all know that fiber optic cables can be divided into single mode and multimode fiber cables, but single mode fiber optic cables can be with UPC or APC polished connectors, while multimode fibers are not made with APC connectors. When we talk about the insertion loss, fiber optic attenuators have to be mentioned, it also has the diffent db to choose, as for the more knowledge about it, please always pay close attention to.

Fiberstore, you know, it offers kinds of fiber cables to choose, the different connector series all available for UPC/APC version, and we can also provide SM, MM, OM3 cables, simplex and duplex option, 0.9mm, 2.0 mm, 3.0mm cable diameter for choose, as for the fiber length, it can be customized according to your requirements.

As HD content becomes the norm in video and broadcasting industry, the limitation to transporting HD video on a network have a bigger impact on budget, responding to this demand in HD video transmission, FiberStore releases the 3G HD digital video SFP transceiver families address issues raised by the data-scrambling algorithms used in DV, enabling digital video to be transported over optical network using standard transceivers,” says Dan Ligon, director and principal analyst for SMPTE. “We are ensuring that we meet this demand in a highly-efficient and cost-effective manner, while providing a superior service experience to our customers.

Digital Video SFP transceivers are designed to affordably transmit SDI, HD-SDI, or DVB digital video component signals over fiber using standard optical transceivers. It is a dual channel optical transmitter module designed to transmit optical serial digital signals as defined in SMPTE 297-2006. It supports from 50 Mbps to 3Gbps and is specially designed for transmitting SMPTE 424M/292M/29M/259M pathological patterns video with reach of 10, 20, 40km over single mode fiber.

The digital video SFP transceiver offers a direct and affordable solution to the problems of digital video optical transport. They allow the transport of SDI, HD-SDI, or DVB ASI component video signals over any optical transport system that employs MSA standard optical transceivers.

The increasing demand on today’s higher fiber counts has exploded the development of multi-fiber technology. FiberStore is one of the main manufacturing of MPO/MTP fiber patch cable and cassettes, and many other MPO/MTP fiber interconnection products, which engineers unique MTP solutions using 12, 24, 48 and even 72 fiber MTP ferrules.

What is an MTP Trunk Cable?
An MTP trunk cable provides 12 to 144 fibre connectivity, by using 12-fibre push/pull optical connectors, it minimized errors and reduced spaces. The MTP trunk cable allows for lower bend radii and smaller slack loops. It enables up to 6x the cable tray capacity over traditional bulkier cabling solutions, saving up to 65 percent space. MPO trunk cable features round furcation legs that provide easy routing and improved storage. With the small profile furcation plug, it allows stress free cable mounting, leaves no legs outside the housing and shipped with strain-relief mounting cradles.

What is MTP Extender/MTP Extension Trunk?
The MTP extension Trunk extend subsets of links from zone distribution into equipment zones, which feature pinned (male) MTP connector on one end and non-pinned (female) MTP connectors on the other. It pinned MTP side mates with trunks via MTP connector panels, while not pinned MTP side plugs into modules or harnesses.

What is MTP couplers?
MTP couplers are simple plastic rectangles that hold two MTP connectors together. One cable going into an MTP coupler needs to have a male connector. The other cable must have a female connector. MTP couplers can be either key-up to key-up, or key-up to key-down. MTP cable has a clip on the top of the connector. On a key-up to key-up coupler, the clips are pointed in the same direction on both of the cables. On a key-up to key-down coupler. On a key-up to key-down coupler, the clips are on opposite sides. This also affects the polarity of the signal. Key-up to key-up couplers invert polarity. Key-up to key-down couplers retain the original polarity. This was initially counter-intuitive to me. It made sense once I thought about it though.

What is MTP harness?
An MTP harness breaks out 12 fiber MTP terminations into LC duplex connectors. It connects to trunks through a pinned MTP connector plug into dual fiber electronics ports with LC uniboot duplex connectors. It is occupying less space than 6 duplex jumpers improve airflow for cooling efficiency. By easing handling of cable connections on high-fibre count SAN directors and switch blades, it enables higher density in equipment patch panels. MTP harnesses are available in two lengths: short harness legs for minimal cable slack and long harness legs for mounting flexibility within a cabinet.

In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don’t froget, when you install the fiber optics, you must testing your fiber optic system. Optical-fiber testing is one of the final and most important procedures in installing optical networks.

How to install the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables can be installed in raceways, cable trays,placed in hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. The installation process will depend on the nature of the installation and the type of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Follow the cable manufacturer’s recommendations. Fiber optic cable is often custom-designed for the installation and the manufacturer may have specific instructions on its installation.
b) Check the cable length to make sure the cable being pulled is long enough for the run to prevent having to splice fiber and provide special protection for the splices.
c) Try to complete the installation in one pull. Prior to any installation, assess the route carefully to determine the methods of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in all fiber optic cables for verification of proper installation. Perform the following tests:
a) Continuity testing to determine that the fiber routing and/or polarization is correct and documentation is proper.
b) End-to-end insertion loss using an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be less than the calculated maximum loss for the cable based on appropriate standards or customer specifications.
c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be used to determine cable loss.
d) If the design documentation does not include cable plant length, and this is not recorded during installation, test the length of the fiber using the length feature available on an OTDR, or some OLTSs.
e) If testing shows variances from expected losses troubleshoot the problems and correct them.

From data and voice to security and video conferencing, many of today’s IT infrastructure services rely on fiber optics to transmit information faster, farther, and in greater amounts than ever before. So fiber optics are more and more popularity in our internet. This post will try to answer some of the basic questions about fiber optic cable.

What Is Fiber Optic Cable?

A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. These cables are designed for long distance and very high bandwidth (gigabit speed) network communications.

Single Mode vs. Multimode Fiber Optic Cable

Single mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode fiber-typically 5 to 10 microns. Only a single lightwave can be transmitted at a given time. The small core and single lightwave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

Multimode fiber gives you high bandwidth at high speeds over long distances. Lightwave is dispersed into numerous paths, or modes, as they travel through the cable’s core. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet (914.4 ml), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission. For example, you can try to compare the single mode duplex fiber vs multimode duplex fiber optic cable, and well know they are different.

The Relationship between Fiber Optic Cable and Fiber Patch Cord

A fiber patch cord is a fiber optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box. This is known as “interconnect-style cabling”.

What Types of Connectors Should be Used for Fiber Optic Cable?

There are a number of connector styles on the market including LC, FC, MT-RJ, ST, and SC. There are also MT/MTP style connectors that will accommodate up to 12 strands of fiber and take up far less space than other connectors. This connector is intended for use with indoor loose tube no-gel cable constructions. However, the most popular connectors are SC, which pushes in then click when seated, and ST, also known as bayonet style, that is pushed in and twisted to lock. That should be a consideration when making product selections.

What kind of jacket rating and type do you require?

Fiber cable jackets come in many styles. As an example, fiber can be Indoor only, Outdoor only, Indoor/Outdoor, Tactical and it can also have Plenum or Riser ratings.

Jacket color is relatively standardized.

a) Multimode = Orange

b) 50/125um 10G = Aqua

c) Single Mode = Yellow

d) Indoor/Outdoor or Outdoor = Black

e) Custom jacket colors are also available for indoor fiber cables
